767500 ÷ 3 
The aim is to understand the frequency of 3 in 767500.

Let's proceed to step 1:
3 can be fit into 7 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

Let's proceed to step 2:
When dividing 16 by 3, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 15 from 16 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Step 3:
3 goes into 17 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
If we subtract 15 from 17, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

Let's proceed to step 4:
3 can be fit into 25 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 2558.0
If we take 24 away from 25, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Advancing to step 5:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 25583.0
Deduct 9 from 10 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

On to step 6:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 255833.0
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 255833.3
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 255833.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 255833.33 with a remainder of 0.001.
